Abstract
A high speed serial printer having a platen or backing for print-receiving media and printing members for effecting display of indicia in printing lines on the media, including a print head having a printing end and selectively operable printing members; motion translation mechanism for oscillating the printing end of the print head laterally relative to the platen from a starting position for the length of a printing line and return to the starting position, which includes a pivot for the print head having an axis of rotation perpendicular to the plane of lateral movement of the print end, and drive mechanism for oscillating the print head about the pivot to minimize the force required to move the printing end of the print head, swinging of the print head on a pivot being materially more efficient than sliding the entire print head along a printing line.
